Official acts of the Holy See now available online

Entire collections of the Actae Sanctae Sedis (A.S.S.) and of the Acta Apostolicae Sedis (A.A.S.) - i.e., the official Acts of the Holy See from 1865 to 2007 - are available in pdf format, as is the twelve-volume collection of the Actes et documents du Saint-Siège relatifs à la Seconde Guerre Mondiale, published by order of Paul VI starting in 1965, and edited by a specialised group of four Jesuit historians.

These texts represent a documentary resource of inestimable value that is now at the disposal of scholars and all interested persons, free of charge. It is a great contribution to research and information on the history and activities of the Holy See. (Holy See Press Office)
